Subject: [TCP]: fix D-SACK cwnd handling
X-Git-Tag: v2.6.24-rc2~132^2~1
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=94d3b1e586f6d4c7150501bde284c544ce99073c;p=pandora-kernel.git

[TCP]: fix D-SACK cwnd handling

In the current net-2.6 kernel, handling FLAG_DSACKING_ACK is broken.
The flag is cleared to 1 just after FLAG_DSACKING_ACK is set.

        if (found_dup_sack)
                flag |= FLAG_DSACKING_ACK;
	:
	flag = 1;

To fix it, this patch introduces a part of the tcp_sacktag_state patch:
